I've only read manga but have heard that the anime is just as good.Monster

Currently watching now, and it's such a well written psychological thriller. It follows a genius surgeon falsely accused of murder while he unravels a twisted past connected to one of his patients. Very mature, very grounded, very suspenseful. It's fully available on youtube dubbed/subbed.
It's so good that I'd even recommend it to those who typically hate anime. It's one of a few manga/anime that I don't think will feel out of place at all if they adapt it into a live-action TV series.
